Title: Bipolar transistor and manufacture thereof
Inventor: MORIMOTO TAKASHI
IPC: H01L29/72
Filed: 1986-10-31
Abstract: PURPOSE:To improve the planar uniformity of a diffused emitter layer, and to enhance the emitter efficiency by composing the emitter of a metallic silicide film, a diffused layer formed under the metallic silicide film and a silicon oxide layer formed in a boundary region between metallic silicide film and the diffusion layer. CONSTITUTION:An emitter forming region is exposed, the periphery of an emitter region is coated with an insulating film 9, a metal is deposited, and the ions of an impurity for shaping an emitter diffusion layer are implanted in high concentration by energy where the ions are stopped in a metallic layer 3. The surface of the metallic layer 3 is coated with a heat-resistant film 6, and an silicide reaction is generated through annerling. Enzyme contained in the metal is segregated to the silicon side by the formation of an silicide, and an extremely shallow silicon oxide film layer 2 is formed just under the silicide 4. When the resistance of the silicide is lowered through heat treatment, the impurity more than a precipitation limit in the silicide is precipitated on the interface of the silicide 4 and silicon 2, and the extremely shallow emitter diffusion layer is shaped. Accordingly hole currents are reduced in the presence of the silicon oxide layer, thus improving emitter injection efficiency.

Title: Pretreatment of sample
Inventor: TOKUDA TOSHIO
IPC: G01N30/64
Filed: 1986-11-04
Abstract: PURPOSE:To achieve an anion detection with a high certainly, by passing a sample liquid containing cation of bivalent or higher valency through a cation exchange resin with univalent ions (excluding H<+>) as counter-ion before it is analyzed using an alkaline elution liquid. CONSTITUTION:When an alkaline elution (e.g. p-hydroxy benzoate, carbolic acid and benzoic acid) is used, it often obstructs the determination of desired ions if, for example, tap water is injected without pretreatment. To remove this obstruction, a sample is pretreated by a cation exchange resin (a resin having acid group such as sulfonic group and carboxylic group) with univalent cations (e.g. Li<+>, Na<+>, NH4<+>, K<+>, Rb<+> and Cs<+>, excluding H<+>) as counter-ion. So that, a pretreatment column having a tube 20 filled with an ion exchange resin 22 is used. The ion exchange resin 22 is held with a filter 24 fixed at the top and the bottom thereof. A sample is passed through a pretreatment column with an injection cylinder inserted into an injection cylinder insertion port 21. Thus, ions of bivalent or more in the sample are removed by being replaced with the counter-ion of the cation exchange resin.

Title: Voice recognition system
Inventor: FUJIMOTO JUNICHIRO
IPC: G10L15/10
Filed: 1989-10-05
Abstract: PURPOSE:To improve the noise resistance ability of a voice recognition device by searching for a part where maximum similarity is obtained for a normal standard pattern while an input pattern is shifted. CONSTITUTION:The system has a part 3 which converts a voice into a feature parameter, a part 8 where standard patterns which are registered previously are stored, and arithmetic parts 7 - 12 which calculate similarity between the input pattern and standard patterns. Prior to the calculation of the similarity, the pattern of the input voice is weighted more at the center part than other parts and while the obtained pattern is shifted on the respective standard patterns, similarity is calculated; and the part where the maximum similarity is obtained is colleted as a temporary start end. Therefore, even if the head or tail of the input voice is absent, that is compensated to some extent and the collection is carried out. Consequently, the noise resistance ability f voice recognition can be improved.

Title: Electrostatic deflection-type cathode-ray tube
Inventor: SEKIDA MASAYUKI
IPC: H01J29/74
Filed: 1984-12-11
Abstract: PURPOSE:To prevent bad influence on high frequency characteristics caused by impedance of lead wires and make any side pin needless by nearly conforming the impedance of in-tube lead wires passing from traveling-wave-type deflection system to the base pin, to the characteristic impedance in the deflection system. CONSTITUTION:The line impedance Zw of in-tube lead wires 15a and 15b is expressed Zw=276log10d/a in case they are parallel wires, and the actual characteristic impedance ZL becomes ZL=KZW. When a line diameter of 2a=0.75mm and mutual distance of d=20mm are set up, the characteristic impedance is obtained in ZL=about 300OMEGA (K=0.63). Since the line impedance can be conformed to the characteristic impedance (about 300OMEGA) of traveling-wave-type deflection systems 1a and 2b, generation of reflection and distortion of signal waves can be prevented, enabling any side pin to be needless.
